Title: Amplitude adjusting device
Inventor: SHIMIZU KEIKO
IPC: G11B7/085
Filed: 1993-12-02
Abstract: PURPOSE:To improve amplitude adjusting accuracy by monitoring the binary signal of a tracking error(TE) signal and fetching a peak hold value after judging that the peak of the TE signal is surely held. CONSTITUTION:At first, a peak holding means 8 is reset. Then, edges of a TE binary signal (the output of a binarizing means 10) are counted with a couting means 11. The counting means 11 outputs a signal fetching command OK to an MPU 9 when edges become a prescribed line number and then the MPU 9 fetches a peak hold value. Further, the MPU 9 obtains a ratio between a fetched peak hold value and an optimum amplitude value to control the amplitude of the TE signal with a gain changeover means 7 according to the ratio.

Title: Image forming device
Inventor: KODAMA HIDEAKI
IPC: G03G15/16
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To perform a stable transfer regardlessly of the states of a recording paper and toner by detecting the electrostatic capacity between a member for applying a transfer charge to a transfer film and a photoreceptor and indirectly checking the resistance value of the recording paper and the deteriorated state of the toner based on the value of the detected electrostatic capacity. SOLUTION: When a key for executing transfer output adjustment processing provided on a control panel is depressed, a CPU 14 obtains the electrostatic capacities of the recording paper and the toner from the value of a current flowing through a transferring part and decides whether the electrostatic charge quantity of pretransfer toner and the resistance value of the recording paper are reduced or not, from the obtained values. As the result of the decision, when the electrostatic charge quantity of the pretransfer toner is at the optimal value or below, the grid voltage of a pretransfer charger is increased. Further, when the electrostatic capacity and resistance value of the recording paper are out of the optimal value, a voltage applied to a transfer roller 38 is decreased by a fixed level.  Thus, the toner remaining on the photoreceptor 23 can be reduced by reverse electrification in the transferring part.

Filed: 1993-12-03
Abstract: PURPOSE: To precisely determine necessity of maintenance by providing a comparing means which compares accumulated wheel slipping quantities and generating a maintenance signal in response to a prescribed minimum difference between them so as to display the possibility of the existence of a problem in a brake system. CONSTITUTION: The defined wheel slipping quantities of each wheel with respect to vehicle braking operation of this time and after this are accumulated in the memory of a computer.
